Female patient, 53 years old, diagnosed in August 2021 with invasive ductal breast carcinoma, unspecified type, grade III, in the right breast. Oncologic treatment was neoadjuvant chemotherapy from October 2021 to April 2022, with subsequent quadrandectomy-type surgery in May 2022. Adjuvant therapy included capecitabine chemotherapy and 15 radiotherapy sessions, which was completed in October 2022. In August 2022, she was referred to the outpatient physical therapy clinic complaining of fatigue with minor exertion, impairment in activities of daily living, and classic signs and symptoms of hand-foot syndrome such as pain, burning, and difficulty performing hand and foot movements that interfered with performing activities, including walking, raising the possibility of interrupting chemotherapy. During physiotherapy assessment, the following steps were performed: On inspection, the surgical scar was found to be in good condition, without significant adhesions; the skin of the thoracic region with mild erythema, classified as grade I radiodermatitis. On palpation, the surgical scar was in good condition, without adhesions, and the skin around the scar showed mild erythema, consistent with grade I radiodermatitis. Goniometry of the right upper extremity (MSD) revealed flexion (150°), extension (45°), and abduction (149°). Left upper extremity (MSE) goniometry revealed flexion (170°), extension (40°), and abduction (130°). Perimetry revealed no changes consistent with signs of lymphedema.
Initial treatment consisted of two weekly physiotherapy sessions aimed at maintaining and improving range of motion, reducing symptoms of cancer-related fatigue (CRF), and reducing symptoms of hand-foot syndrome such as burning pain. hyperesthesia, hyperemia, and scaly tissue changes. The established procedures for physical therapy treatment were: active kinesitherapy for the upper limbs, aerobic exercise with an ergometric treadmill or stationary bicycle, with progressive intensity (mild, moderate, vigorous), and FBM with LED for hand-foot syndrome.
The FBM protocol on the palmar surface was performed with the Endophoton® device - KLD – Brazil, with continuous mode and punctual technique. The applicator cluster has an effective irradiation area of 7.85 cm², with twelve LED points, power of 0.04 W per point, total power of 0.48 W per irradiation area, with 6 red LED points with a wavelength of 658 nm and 6 infrared with 858 nm. The dose used was 4 J/cm² for both wavelengths, with an average application time of 1 minute and 20 seconds at each point, with a distance of 1 cm between points. A Sportllux Advanced® LED blanket with 72 LEDS was applied on the sole of the foot, 36 with a wavelength of 660 ± 20nm (red) and 36 with a wavelength of 850 ± 20nm (infrared). The average power of each LED is 8 mW, total 0.58 W per irradiation area, at a dose of 4 J/cm² and a duration of 10 minutes (parameters provided by the manufacturer of the device cannot be changed), on the sole of the foot and toes.
Kinesiotherapy consisted of a combined protocol of free exercises with a stick, a ball, dumbbells, and elastic bands, with progressive loading and resistance. The exercises aimed to raise the upper limbs above head level, in addition to exercises with a Swiss ball for trunk control and breathing exercises, consisting of 3 series of 10 to 15 repetitions each. Aerobic exercises were performed for 20 minutes on a treadmill or a bicycle, increasing the training heart rate (HR). Maximum heart rate was determined by calculation: HRmax = 220-age, keeping a target value HR of 60 to 70% of HRmax and a perceived exertion between 13 and 16 based on the scale BORG. In the first 10 minutes, the exertion intensity was 13–14; in the remaining 10 minutes, the exertion intensity was increased to 15–16. The physiotherapy protocol, established twice a week, was alternated, with kinesitherapy and aerobic exercise on one day and the second session focused on treating the symptoms of SMP with photobiomodulation. In addition, the patient was asked to maintain continuity of activities at home to support the physiotherapy treatment.
After the first week of physiotherapy, a significant improvement in SMP symptoms was observed. The patient reported a reduction in the burning sensation and pain on the palm and soles of his feet, allowing her to perform pinching movements with her hands and walk longer. As for the appearance of the skin, a decrease in the cyanotic color on the extremities was observed. After 4 weeks, improvement in skin integrity was observed with complete resolution of plantar hyperkeratosis, even with continued chemotherapy treatment.
After the fourth application (four weeks), it was observed that after the formation of a crust with initial thickening and subsequent peeling of the skin, there were characteristic signs of improved vascularization, increased proliferation of epithelial cells, possible proliferation of fibroblasts (fibroplasia) and skin regeneration, culminating in restoration of vitality and positive effects on skin quality. These benefits were also observed with the continuation of adjuvant chemotherapy, with the patient reporting a significant improvement in burning sensation and absence of pain at the end of the fourth application, allowing her to resume daily activities and continue chemotherapy. It was recommended that skin care be continued and hydration with moisturizers be maintained according to physician recommendations, in addition to guidance on physical exercise, which is essential for maintaining range of motion and managing cancer fatigue. The results are shown in images 1 and 2 before and after a week of treatment. Figure 3 displays the outcome following the fourth intervention.
The symptoms of CRF improved from the second session, even in the first week of treatment, with the protocol of combined physical exercises of moderate to high intensity. The patient reported a reduction in the sensation of fatigue and pain, as well as an improvement in the perception of effort, which allowed a better adaptation to the proposed exercises. In this way, the treatment had a positive effect on quality of life, ensuring a greater ability to perform daily activities.
